Unite said companies which have paid out huge amounts of money in compensation in recent years were still targeting union members for unfair treatment.

The union is taking action in the High Court on behalf of workers whose names were kept on a list drawn up by the Consulting Association.

The organisation, which kept a list of over 3,000 construction workers regarded as union activists or who had raised health and safety issues, was closed down in 2009 following a raid by the Information Commissioner's Office.

Unite said it was also issuing legal proceedings against a number of leading construction firms.

Unite assistant general secretary Gail Cartmail said: "The disgusting practice of blacklisting has not disappeared. Blacklisting will not be stamped out until the Government brings in effective laws.

"Unite are uncovering fresh cases of contemporary blacklisting which demonstrates why urgent action is needed to end blacklisting once and for all.

"It is simply outrageous that companies who have been caught blacklisting and have ruined the lives of construction workers, have escaped virtually scot free and continue to be rewarded with public sector contracts."
